WINDOW GUIDE.

Application filed July 9,

i This invention relates to devices for preventing the rattling of structural compo-' nents, and is specially applicable to the This invention provides an improved construction of structural component with which there is associated a cushioning device which engages another component and prevents it rattling.

This invention accordingly comprises a strip of metal, celluloid or other similar material, whichis formed with perforations, projections or-the like at spaced intervals along its length, with which perforations a strip of felt or'other sound-deadening material' is adapted to be engaged, so as to form 'a-series of pads or cushionson the strip; I

The invention further consists in the improved rattle-preventing devices to be hereinafter described.

' Referring now to the accompanying drawings Figure 1 shows a view in perspective of a window-channel for a motor vehicle con-v structed according to the invention;

Figure 2 shows a part side elevation, and

Figure 3 a cross-section of awindow fitted with the channel shown in Figure 1; Figure 4 shows an elevation of a windowchannel with a modified form of perforation to that shown in Figures 1, 2 and 3.

Figures 5 and 6 show a side elevation and cross-section of a modified construction of window-channel.

In carrying the invention into effect according to one form, and as applied by way of example to a motor vehicle having sashless or frameless windows of plate glass, a metal strip 1, Figures 1, 2 and 3,

is constructed of channel-section, having perforations 2 formed on the bottom and sides-thereof.

The perforations 2 in the present example are rectangular form and are grouped in pairs, the holes of each pair being separated from oneanother by a bridge-piece 3 in Window 1924. Serial No. 725,018.

of metal about 2 mm. wide. The distance between the centres of the bridge-pieces is about 20 mm. 7

The groups of perforations on the bottom of the channel are in staggered relationship to those formed on the sides. I i

Strips of felt I are threaded through the perforations and over the bridge-pieces on the bottom and sides of the channel, so that a series of spaced pads or cushions 5 of felt are formed both on the inside and outside ofthe channel by the use of only three strips of felt.

In Figure lens of the sides of the channel is shown with the felt threaded through the perforation therein, while the other side and the bottom are shown without the felt for purposes of illustration.

The pads on theinside of the channel are almost continuous, being only separated from onefanother by the width of the bridge-pieces, while on the*-,outside of thechannel the pads are separated from one another by the extent of the metal strip between the groups of perforations and amounting in the present example to about 10mm. I A channel-strip such as that above described may be attached at its upper ends by means of a single screw 6 to each side of the frame 7 for the window 8, so as to allow the window when raised to move the ohan nels laterally 0n the screws as pivots, to seat 1 the window on its ledge and thereby retain it in the raised position.

A third channel-strip constructed as above described may be fastened to the top of the window-frame for receiving the upper edge of the window when the latter is raised.

In the above arrangement it will be seen that the channel-strip not only prevents rattling between the window and the channels, but also between the channels and the window-frame.

By pressing the end bridge-piece hard down on the felt, the latter is effectively gripped and retained in position, thereby preventing rucking of the material. Further, by suitably bending the bridgepieces, the thickness of the projecting portions of the pads on the outside of the channel may be adjusted as desired.

In some-cases, instead of the arrangement of the perforations above described, there Further, projecting tongues may be formed, which are pressed out on one or both sides of the metal strip and a strip of felt attached to one or both sides thereof to form pads or cushions on one or both sides of.

the strip, as desired. An example of this method of construction as applied to a strip of channel-section isshown in Figures 5 and 6. In these figures, tongues 11 are pressed out on the bottom and sides of the strip 1 and strips of felt 12 are passed under the tongues to form the pads or cushions.

Again, the rouping of the perforations may be modi ed to obtain other arrangements of pads or cushions.

Instead of felt, any other suitable sounddeadening material may be used, while celluloid or other suitable material may be used instead of metal.

Although the invention has been described as applied to a frameless or sashless window for a motor vehicle, its use is not limited to this application, as it may be applied to other forms of windows for motor vehicles, and also to railway carriage windows and other structural components.

It is to be understood that the above examples of the invention are simply to be regarded as typical only, and not as in any way restricting the invention thereto, as modifications may be made in the examples above described, without departing beyond the scope of the invention.

What I claim as my invention and desire to secure by Letters Patent is 1. In a window-channel for sliding win-- dows, the combination of a rigid channelsectioned bar that is perforated at intervals along its length in its web and in its flanges, and a plurality of strips of cushioning material respectively associated with the said web and flanges, each strip being threaded through said perforations to provide a series of cushions spaced apart along the length of each side of each wall of the channel-sectioned bar.

2. In a window-channel for sliding windows, the combination of a channel-sectioned metal bar that is perforated at intervals along its length in its web and in its flanges, and a plurality of strips of cushioning material respectively associated with the said web and flanges, each strip being threaded through said perforations to providea series of cushions spaced apart along the web and along the flanges respectively, with the cushions in the web in staggered relationship to the cushions in the flanges.

3. The combination of a channel-sectioned metal bar perforated at intervals along its length in its web and in its flanges and formed with tongue associated with said perforations, and -a plurality of. strips of cushioning material threaded respectively 1 in the perforations of the web and of the flanges, said strips being retained against endwise movement by interlocking with said tongues.

4. In a mounting for a sliding sashless window, the combination of a channel-sectioned metal bar perforated at intervals along its length in its web and in its flanges, strips of cushioning material threaded respectively in the perforations of the web and of the flanges to provide a series of cushioningpads inside and outside the bar, and a ivotal mounting for-one end of the. bar, su stantially as set forth.

In testimony whereof I afiix my signature.
